@someone in the page

@xxx Regularly obtains the name and queries the database in the background to generate records... Or is there another way to write it? Find out. Suddenly curious.
I saw that there is as.js on the front end but I didn’t look at the source code...

Querying is always necessary, right?

I can’t think of anything other than what you think.

When the record containing @ is stored, it is stored normally. Then when it is retrieved for the first time, it is removed and matched regularly. Then the database obtains the @ user information, generates a record containing the id, and then caches this (Instead of the original record content of the database), so that you don’t need to fetch it from the user database next time.

In addition to use? Is there anything else?
